hi ezer
do tell us more about your pond - i've always wanted a pond like that instead of those modern thingy with all the pond-liners and stuff.
i guess pond like that is a natural ecosystem in itself do you need to clean it off weeds from time to time and how do you tell whether the fish is sick so you can quarantine and treat it?
what i really want is a in-the-ground pond at my back yard (well, i can only afford about like mayb 2ft by 6 ft) and keep an arowana in it, try to create it's natural environment and feed it fish pellets or algae pellet. i have read that the arowana lives in rainforests river so it would be unnatural to keep them in a tank but then if i can only afford 2ft by 6 ft pond, who am i to critise those who keep their arowans in a tank.
what is the smallest size pond i can have for koi? i i better not dream about them though, i have barely enough to keep my cats and i going...
